Answer:
166.8 pounds.
Step-by-step explanation:
Let b be the number of batches baked and f be the total weight of flour.
We have been given that a cupcake factory has already used 22.8 pounds of flour today.
They are now making cupcakes that require 8 pounds per batch, so the weight of flour used in b batches will be 8b.
The equation representing the total weight of used flour is given as:
To find the total weight of flour used, when 18 batches are baked we will substitute b = 18 in our given equation.
Therefore, the total weight of flour used in baking 18 batches will be 166.8 pounds.
